[Elecraft] KXPA100 connections

[Don Wilhelm]

Rick,

The cable kit makes it 'plug-n-play'.  Well worth the $39.95 IMHO, but 
may vary on how you value your time and frustration level.

Since it is unlikely that I will be able to find a cable with an RCA plug on one end, and a 2.5 mm stereo plg on the other, without tip wire, it looks like a custom job.

>> Yes, the KXPA100 end is an RCA plug and that is clearly shown, but the other end must match the transceiver and since several types of connectors are used on transceivers for KEYOUT, the KXPA100 must be ambiguous about the connector on the transceiver end (i.e. the FT-817 uses a DIN connector IIRC).
